My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.

“We chose to use an insulated house wrap beneath the new prefinished siding. The installation work was clean and precise and very detailed. We’re very happy with the appearance of the house, and so far the house wrap has made an improvement over what was a drafty condition, and the house feels more uniformly comfortable. The carpenters and painters did a great job with minimal punchlist. We’re looking forward to decades of low maintenance and a more comfortable space.”
